Question for Ram 2500 owners
1 Attachment(s)
I currently have a Ram 2500 Cummins and I'm running 33X10.5 tires with a leveling kit, and tied back inner fenders. Has anyone tried running 35 X 12.5s without a lift and without rubbing? Specifically, anyone with a pre 2013? The reason for the year is, the 2013 truck got new suspension which I believe made it sit higher from the factory.

The rear will be fine, front will rub. Need at 3” leveling kit at least and still have to do some trimming |

What's the offset of your wheels? The front height of the newer 4th gens my be a tad taller, but I think the rubbing has more do with the offset of your rims. I bet you can run 35x12.5s with just a 2" leveling kit as long as the wheel's offset isn't to positive (as in stock offset) or a negative offset. A stock offset wheel and 35s will cause the tires to rub on the control arms, and going with a 0 to negative offset and 35s will push the wheels to far out causing the tires to rub somewhere on the fender. I say this because I just traded in a 3rd gen 2500 mega cab with a 2" leveling kit running on 35x12.5R20 with a +18 offset rim and it never rubbed. I traded in my mega cab for 2018 Ram 2500 crew cab and had the dealership install a 2" leveling and just swapped over my setup and still no rubbing. A good place to get an idea about what will work and what won't is customwheeloffset.com gallery. Here's my old truck.

And here's the new truck with the setup swapped over

Customwheeloffset.com is great. You can search your year and view tons of trucks with different applications. When you see a setup you like, all the specs for the build will be listed, including extra info like rubbing/no rubbing, trimming/no trimming, etc.

A lot has to do with the wheel size, offset and backspacing.
I have a set of 20x9's with +18 offset and 5.75" backspace. I run 35.12.50's with no rub. I have a 1" lift in front. My buddy has a similar truck with a 3" leveling kit. Runs the same tire as me, same wheel size at 20x9, but with 0 offset and 4.5" backspacing it still rubs even though its way taller than mine. Just something to think about. |
Another good site to check out is www.wheel-size.com. It doesn't have a gallery, but it has a rim & tire size calculator that allows you to put in different wheel and tire parameters. You can compare OE setup to whatever wheel and tire setup you want.

Thanks guys.

I am speaking from a truck that has 20x10’s. It’s worth the leveling kit and a little trimming for the look that 10 wides give compared to 9 wides imo.

Definitely a great looking truck.
Update: I had a local shop test fit a BFG AT 35 X12.5, which actually measures out to 34.25". The tire rubbed to the point where it prevented a full left turn. I went with a 295 60 20 which measures out to 33.5 x 11.5". With my offset and the level kit on a 2011, that's as big as I can go. |

Your trucks are to clean!! 2015 2500 rear air ride leveled with 35 X 12.5 X 20, Force Wheels 20X10 -24 off set. Had to do a little trimming of the plastic fender wells

Cool truck. |
I have an 09 Ram 2500 with a 2" leveling kit and 35 x 12.5 and toyo a/t rear is fine, front only rubs on left turns at about 3/4 crank. I just let it rub, it rubs on the inner fender plastic and I'm used to it from years of running radius arm suspension on a previous truck that rubbed on both sides. I could prob trim it away and it wouldnt rub anymore. That being said I used to have BFG Mud Terrain 35x12.5 on same rims and didn't rub at all. I think the corners of the muds were more rounded than the a/ts
From what the leveling kit has done to my suspension geometry though I wouldn't run a leveling kit again. Spend the money (1K+) on a good 3" lift from Carli and keep the proper geometry and you'll have a truck that can handle freeway speed bumps properly, unlike mine that gets pretty sketch if I am unloaded and hit a pothole. Loaded its no factor. |
I have stock 17. 35X11.5 Nito ridge grapples on 20X9 with +20mm offset fuel wheels. No issues.
